Answer:
3) One-sided,compare two populations
Step-by-step explanation:
A manufacturer wants to investigate the whether there is an increase in the mean gas mileage of mid-sized sedan having new type of tire compared to mean gas mileage of mid-sized sedan not having new type of tire.
So, there are two populations :
population 1 : mid-sized sedan having new type of tire.
population 2 : mid-sized sedan not having new type of tire.
So, two populations are being compared.
Also, A manufacturer is investigating whether there is an increase in mean gas mileage.The alternative hypothesis will be right tailed and so, this corresponds to one sided test.
Answer:
x = 1, y = 2
Step-by-step explanation:
x + y = 3 => 2x + 2y = 6
2x + 3y = 7
-)2x + 2y = 6
=> y = 1, x = 2
Ok, so if he walks 4 miles per 64 minutes, or 4 miles/64 min which will
reduce to 1 mile/ 16 min, then the numbers of miles he walks in a given
number of minutes would be
1/16 * number of minutes
The question states we represent miles with y and number of minutes with x, so...
y = 1/16x
So let's check it...
How many miles (y) in 64 minutes (x)
y = 1/16x
y = 1/16 * 64
y = 64/16 = 4 miles
Yep! It checks!
